He has yellow hair with blue eyes, and bright golden yellow flame. He wears a suit of a noble child (Oji Lolita). He wields a giant sword called Blutsauger that has the capability to damage severely his opponents even with the slightest contact, but not satisfied with it, wants Nietono no Shana for himself.

He is eliminated by Shana when she tricks him by throwing Nietono no Shana and slashing him in four pieces.
